Renesas Claims First AI Employed in Cortex-M85 Processor with Helium Tech
This article is part of our embedded world 2023 coverage.
At embedded world 2023, Renesas Electronics will have live demonstrations of AI and machine learning implementations on an MCU based on the Arm Cortex-M85 processor. They're intended to show the improvement in AI/ML solutions enabled by the Cortex-M85 core and Arm’s Helium technology.
At the Renesas stand in Hall 1, Stand 234, demonstrations include a people-detection application developed with Plumerai that identifies and tracks people in the camera frame in varying conditions. Another demo showcases a motor-control predictive-maintenance use case with an AI-based unbalanced-load-detection application.
Delivering over 6 CoreMark/MHz, the Cortex-M85 serves IoT use cases that need the best compute performance with DSP or ML capability. The Arm Cortex-M85 processor with Helium technology, and Arm’s M-Profile Vector Extension, are available as part of the architecture. Both demos will illustrate the performance uplift made possible by the application of this technology in AI use cases.
“We’re proud to again lead the industry in implementing the powerful new Arm Cortex-M85 processor with Helium technology,” said Roger Wendelken, Senior Vice President in Renesas’ IoT and Infrastructure Business Unit. “By showcasing the performance of AI on the new processor, we are highlighting technical advantages of the new platform and at the same time demonstrating Renesas’ strengths in providing solutions for emerging applications with our innovative ecosystem partners.”
“We’re excited to take part in this groundbreaking demonstration,” said Roeland Nusselder, CEO of Plumerai. “Arm’s Helium technology supported on the new RA MCUs with the Cortex-M85 core significantly accelerates the Plumerai inference engine. This performance uplift will enable our customers to use larger and more accurate versions of Plumerai's People Detection AI, add additional product features, and extend battery life. Our customers have an insatiable appetite for adding new and more accurate AI features that run on a microcontroller. Together with Renesas, we are the first to fulfill this demand.”
The new Cortex-M85 core supports Arm TrustZone technology, which along with Renesas’s integrated cryptographic engine, immutable storage, key management, and tamper protection, provide an integrated secure-element functionality. The Armv8-M architecture also brings Pointer Authentication/Branch Target Identification (PAC/BTI) security extension, offering enhanced mitigation from software attack threats and enabling PSA Certified Level 2 certification.
